How to query on table returned by Stored procedure within a procedure

Question

I have a stored procedure that is performing some ddl dml operations. It retrieves a data after processing data from CTE and cross apply and other such complex things.

Answer 1

Edit This wouldn't be suitable for 4 tables but you say in the comments you can convert to return one.

You can use OPENROWSET for this (Doesn't appear to be mentioned in Paddy's linked question). This requires adhoc distributed queries enabled.

Example usage

SELECT  *
FROM    OPENROWSET ('SQLOLEDB','Server=(local);TRUSTED_CONNECTION=YES;','set fmtonly off exec master.dbo.sp_who')
AS tbl

Answer 2

I think that your question is similar to this one:

Access to Result sets from within Stored procedures Transact-SQL SQL Server

Answer 3

This is not possible.

The only way I can think of is to insert the results from the Stored Proc in to a temp table and query the temp table. This won't work in your scenario as you are returning 4 tables.

Could you not rewrite the query you are interested in as a function or view?

EDIT:

You would do something along the lines of this (only if the Stored Proc returns one table)

Create Proc dbo.usp_FetchUsers

as

begin

Select UserId, UserName
From Users

End
Go

Create Table #t
(
UserId int,
UserName varchar(50)
)

Insert Into #t
Exec dbo.usp_FetchUsers

Select * From #t
Where UserId = 4

drop table #t
